EVISCERATORBS ITARY MOVABLE PLATFORM.

To aZZ whom it may concern:

Be it knownthat I, A VIN O. 'LUNDELL, a citizen of the United States, and a resident of the city of Chicago, in the county of Cook and State of Illinois, have invented certain new .and useful Improvements .in an' Eviscerators Sanitary Movable Platform; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the numerals of reference marked thereon, which form apart of this specification.

This invention relates more particularly to an improved type of a movable endless platform adapted to be used in combination with a viscera table and with a carcass conveyor and simultaneously operable therewith but at a reduced rate of speed to permit an eviscerator to stand upon the endless platform and be carried thereby while eviscerating carcasses the removed viscera of which are deposited for inspection in separated compartments of the viscera table.

It is an object of this invention to provide an improved device for eviscerating carcasses in a sanitary manner. Q

It is also an object of this invention to provide an eviscerators movable, sanitary platform in combination with a viscera 1nspection table and acting to support the v table and the traveling eviscerators platform.

eviscerator While removlng the viscera from carcasses for deposit on the inspection table.

Another object of the invention is to provide a movable evisoerating platform adapted to be' operated simultaneously with a viscera table, but .at a reduced rate of speed to permit aneviscerator standing on the movable platform to remove the viscera from carcasses carrled along by an overhead conveyor.

A further object of this invention is to provide a movable eviscerating platform wherebyan eviscerator on the movable plat- Specification of Letters Patent. Patented Applicationfiled July 3, 1920. SerialNo. 393,942. I

provide a machine whereina viscera conveyor and a" carcass conveyor traveling at thesame rate of speed are arranged with a movable eviscerating platform disposed therebetween and operable at'a lower rate of speed, and having means associated therewith for sprayingthesame to keep the platform in a sanitary condition so that viscera accidentally falling thereon will not be con taminated.

It is an important object of-this invention to provide a machine wherein carcasses conveyed by a movable overhead conveyor adjacent a traveling table are adapted to have the viscera removed therefrom and "placed upon the table by an eviscerator stationed on a sanitary traveling platform driven simultaneously with the table and conveyor. i

Other and further important objects of this invention will be apparent from the disclosures in the specification and drawings.

The invention (in a preferred form) is illustrated in the drawings and hereinafter 'more' fully described.

On the drawings: Figure 1 is a top plan view-of a machine provided with an eviscerating platform embodying the-principles of this invention.

Figure2 is a sectional view taken on line 22 of Figure '1, showing parts in elevation.

Figure 3 is a top plan view'of the viscera Figure dis a side elevation thereof. I

Figure 5 is a sectional end view takensection The viscera carrier or table comprises a supportlng frame 1 havlng a transverse shaft 2 journalled in suitable stationary-bearings at one end thereof, and 'ajtransverse shaft '3' journalled in EadjuStably supported bearings 4 at the opposite-end of said frame. The bearings fare slidably disposed within guide members 5 and areadapted to be adj-ustedloy means of screwbolts 6. Keyedor otherwise'secured'on one projecting endof gear 21.

' the shaft2 is a driving pulley or wheel 7 adapted to be driven by means of a power belt 7 A sprocketgear 8 issecured on'the other projecting end of the shaft 2'and has an endless sprocket chain 9 trained there- Attached transversely of the chains 11 are a plurality of fiat cross members, slats or cleats 14 provided at both ends with integral outwardly turned flanges 15. The slats 14 form a movable endless viscera conveyor or table having compartments formed by rigidly securing to certain'of the slats 14:, transverse partitions or plates 16. A shield ,or housing 17 is secured to the frame 1' to enclose the sprocket gear 8 and the upper portion of the driving chain 9.

Positioned adjacent one side of the loading end of'the viscera carrying machine is an eviscerating device comprising a supporting frame18. A shaft 19 isqournalled in stationary bearlngs 2O supported on the frame 18 at the loading end thereof. The

rear or inner endof the shaft 19 projects beyond the side of the supporting frame 18 and has'secured thereon a lar e sprocket The driving sprocket chain 9 is trained around the gear'21 to transmita drive from the pulley 7 to the shaft 19 at a'rate of speed less than the speed of rotation of the shaft 2. A transverse shaft-22 is ournalled' in adjustable bearings23 at the end of'the frame 18 oppositethe shaft 19. The bearings 23 are slidably mounted in horizontal members of the frame 18 and are adapted to be adjusted by means of screw bolts 24, which have threaded engagement with upright members of the frame 18.

Rigidly secured on each of the shafts 19 and 22 are sprocket gears or wheels 25, around which endless conveyor chains 26 aretrained. The chains 26 are equipped with rollers 27, which run onguide tracks or rails '28 secured longitudinally on'the supporting frame 18. Attached; transversely to the chains 26 are a plurality of adj acently disposed flat cross members, cleats or slats 29. The slats-29 and the chains 26 form a movable endless platform whereon a butcher oraneviscerator isipermitted to stand while removing viscera from carcasses. The removed viscera are placed upon the movable conveyor .01 table 14 in the compartments :which serve to keep the viscera of different 7 animals separated from one another to elim- 'inate any possibility of healthyviscera from becoming contaminated by diseased viscera.

A perforated horizontal steam I or -hot 1 one end of the eviscer'ating platform. The pipe 30 is connected with a steam or hot water supply pipe 31.

As'shown in Figures 1 and 2, the viscera table and the eviscerating platformare used in combination with 'an overhead carcass conveyor. A conveyor track 32 is provided and leads from a carcass scalding and dehairing machine 33. Traveling in said track 32 is an endless conveyor .chain 34 trained at one end around a sprocket wheel 35 mounted on a vertical shaft 36. The

sprocket chain 34 has depending pushers or fingers 37 secured thereto, each of which engages a carcass carrying gambrel carriage 38 traveling on a guide rail 39.

A horizontal drive shaft 410 is journalled above the machine and is provided on one end with a drive pulley 41, driven by a belt 42 connected with a suitable source of power. v

head conveyor is adapted to carry carcasses past the movable platform 29 supported on the frame 18. An eviscerator or butcher is permitted to standon the platform 29 so that the viscera may be removed, by the eviscerator, from a moving carcass. The removed viscera is deposited by the eviscera tor into one of the compartments of the inspection table 14 The successive tableoom partments are each filled with'a viscera fronr the carcass positioned opposite it on the conveyor. The eviscerated carcasses are carried along by the overhead conveyor ad jacent the travelingconveyor tableropposite or adjacent their respective viscera. The

various viscera are carried past an inspector who stands besidethe traveling table and inspects the viscera. If the viscera are free from disease or other objections, they are passed on to be discharged. If, however, a

viscera is found to be diseased or objectionable for otherreasons. it is tagged as it "is-- conveyed'along, as is also the respective carcass which isopposite the viscera and is carried by the overhead carcass conveyor;

-Attention is particularly directed to the arrangement whereby the eviscerator ispermitted-to stand upon the movable platform 1 29 as the viscera is removed from'a moving,

carcass. This arrangement allows the removal of a VISCGIttO be conveniently performed by an eviscerator since the platform 29 is positioned between the moving table 14 and the overhead conveyor. A viscera removed by the eviscerator standing on the eviscerating platform is dumped into one of the table compartments tobe carried past an inspector as already described.

The endless inspection table is operated from the pulley 7, which is operated by the belt 7 connected with the drive pulley on the shaft 40. Rotation of the shaft 2 by the pulley causes rotation of the sprocket gear 8. A drive is thus transmitted to the platform shaft 19 through the chain 9 and the largesprocketgear21. Theplatform29moves slower than the table 14:, since the gear 21 is larger than the gear 8. The upper run of the platform is supported on the tracks 28 by means of the rollers 27. The sprocket wheels 25 on the shafts 19 and 22 act to move the platform chains 26.

Often viscera are accidentally dropped upon the moving platform 29 from which they may be removed and placed upon the traveling table 14. To keep the platform in a sanitary condition to prevent viscera falling thereon from becoming contaminated, steam or hot water from the pipe 30 is sprayed upon the moving platform which is thus thoroughly washed and'sterilized.

I am aware that numerous details of construction may be varied through a wide range without departing from the principles of this invention, and I therefore do not purpose limiting the patent granted otherwise than necessitated by the prior art.

I claim as my invention:

1. The combination with a movable viscera inspection table, of a movable eviscerating platform disposed adjacent the loading end thereof.

2. In a meat handling and inspection machine, the combination with a movable viscera inspection table, of a movable eviscerating platform disposed adjacent the loading end thereof, and means for simultaneously operating said table and platform.
